• How do I base64 encode a string efficiently using Excel VBA?

  - by Matthew Murdoch

  I need to encode a 100KB+ string as base64 in VBA. Are there any built-in functions or COM objects available which will do this as a pure VBA approach is either complex or doesn't scale well at these volumes (see links from dbb and marxidad)?

• How to test if a gawk string contain a number?

  - by Tim Menzies

  In gawk I know two ways to test if a string contains a number. Which is best? Method one: using regular expressions: function method1(x) { return x ~ /^[+-]?([0-9]+[.]?[0-9]*|[.][0-9]+)([eE][+-]?[0-9]+)?$/ } Method two: the coercion trick (simpler): function method2(x) { return (x != "") && (x+0 == x) } Is there any reason to favor the more complex method1 over the simpler method2?

• Support for encoding query string or POST data in YUI ?

  - by faB

  How do you encode a javascript object/hash (pairs of properties and values) into a URL-encoded query string with YUI (2.7.0 or 3.0.0 Beta) ? I want to do the equivalent of Object.toQueryString() from Prototype: I need this to encode parameters for GET and POST requests with YAHOO.util.Connect. It turns out YAHOO.util.Connect has a setForm() method to serialize a form but that still leaves me out cold to encode parameters for GET requests, or the 4th parameter of YAHOO.util.Connect.asyncRequest() to pass post data.

• C: Why some string.h algorithms work slower than simple hand-made ones?

  - by MInner

  For example, strlen() takes about 3*O(n). Why 3? I've wrote a really simple strlen-like function - it works much faster. int string_len(char s[],int &l) { for(l=0;s[l];l++); return l; } Well, some of my friends says, nearly all of string.h algorithms are slower than they should be.
